I'm financing a vehicle how could I get into another one of my choice?
Go buy another one if you can afford it.
If I understand the question correctly, you would like to sell/trade your current car and replace it with another car. Your current car has financing, but you would like to finance the next car, as well..... If you can't pay off the current loan prior to purchasing another car, the current loan balance will have to be paid before the car can be transferred to another person. If you use this as a trade, any finance company will require you to convert this car loan into a personal loan with your current payments or higher. This will impact your credit availability. If you can qualify for future financing of a car with this loan payment continuing to be made, it will reduce the amount of financing you can qualify for, and you can purchase any car you want with whatever financing is still available to you.
